That setup would work well. Although I would take out first: Phantom Blow, because your main attack as a bard should be Cadence spaming. second; Picking only one anthem in your tree and saving a point for the RS tree. third; get rid of Rift Guard and Improved Rift Guard and your points in Nightblade and pick up Bladedancer for Sidesteps. Here's a pretty decent survival support build http://rift.zam.com/en/stc.html?t=0MpcV.xIxhh00oz.EIdVi0szVz with lots of heals and survival cooldowns.
